Hybrid & Electric Vehicle Service

The shift to hybrid and electric vehicles has changed what it means to service a car — and not every shop has kept up. At Northstar Automotive Group in Gormley, ON, Master Mechanic Dawood Motala and his team of certified technicians have invested in the training, tools, and safety protocols required to properly service hybrid and electric vehicles across a wide range of makes and models. From high-voltage battery health checks and regenerative braking service to inverter diagnosis and thermal management system repairs, we provide the specialized care that hybrid and EV owners deserve without sending you back to the dealership for every service need. These are complex, high-voltage systems that demand respect, expertise, and precision — and that's exactly what we bring to every hybrid and EV that comes through our doors.

High-Voltage Battery Health Check

We perform comprehensive high-voltage battery health assessments that measure cell balance, state of charge, capacity degradation, and overall pack condition, giving you an accurate picture of your battery's current health and how much useful life it has remaining.

Hybrid Battery Reconditioning

We recondition hybrid battery packs through controlled deep cycling and cell balancing procedures that restore lost capacity and extend battery life, providing a cost-effective alternative to full battery replacement for packs that still have usable life left in them.

Regenerative Braking System Service

We inspect and service regenerative braking systems that recover energy during deceleration, diagnosing faults in the brake blending logic, hydraulic components, and electric motor controllers that cause reduced energy recovery and inconsistent brake pedal feel.

Electric Motor Inspection

We inspect electric drive motors for bearing wear, winding integrity, cooling system condition, and mounting hardware, identifying developing issues before they result in performance loss or the kind of motor damage that turns a manageable repair into a major replacement.

Inverter & Converter Diagnosis

We diagnose faults in high-voltage inverters and DC-DC converters using specialized diagnostic equipment, identifying the component-level failures that cause power loss, warning lights, and charging issues on hybrid and electric vehicles.

Charging Port Inspection & Repair

We inspect and repair charging ports and inlet assemblies for damage, corrosion, locking mechanism faults, and communication errors that prevent proper charging, restoring reliable charging capability without the dealership wait times and markup.

Thermal Management System Service

We service the thermal management systems that regulate battery and motor temperatures on hybrid and electric vehicles, maintaining the precise operating temperature range that protects battery longevity and ensures consistent performance in Ontario's extreme seasonal temperatures.

12V Auxiliary Battery Replacement

We replace the 12V auxiliary batteries that power the low-voltage systems on hybrid and electric vehicles — a commonly overlooked service item that causes no-start conditions, warning lights, and communication errors when neglected despite the high-voltage pack being fully charged.

Hybrid Coolant System Service

We perform hybrid-specific coolant system service including the separate cooling circuits for the battery pack, inverter, and electric motors, using the correct coolant specifications and procedures that differ significantly from conventional vehicle cooling system service.

Software/Firmware Updates

We perform software and firmware updates for hybrid and electric vehicle control modules, applying manufacturer-released calibrations that improve charging performance, battery management, regenerative braking behaviour, and overall system reliability on supported vehicles.
